Introduction
rename pagegenerators.GeneratorFactory.handleArg() method to handle_arg() due to PEP8 naming convention
What to do:
- rename handleArg() method of pagegenerators.GeneratorFactory to handle_arg()
- deprecate the old method with deprecated Decorator (from pywikibot.tools)
- replace all occurences of this GeneratorFactory.handleArg() with the new identifier. They can be found here
Important hints
- be aware: GeneratorFactory method is handleArg() not handleArgs() because it processes one option only
- a similar deprecating solution can be found for handle_args()/handleArgs() function in pywikibot.bot module
- refer our Coding Convention Guidlines
